In order to render the description as clear as possible, I will describe the machine under separate headings as follows:-1st, a

brief description'of the frame; 2nd, the en- Vvelop feedergrd,` the stamping device; 4th,

the stamp canceler.

The )emmer-The frame is shown clearly in Fig. 2 of the drawings. It consists of a standard 4 having a broad floor plate, where the electric motor 17 6 may be mounted. rThis standard carries a gear casing 3, which is covered by a table 2, `hinged at one end by a hinge 5, 6, 7, and fastened at the opposite endV by a bolt passing through the same and screwed into the lug`9. rEhe table has a raised portion partly throughout its length, as shown by the numeral 10, Fig. 1, and one side of this raised portion carries a wall designated by the numeral 200, Fig. 1. The raised portion is intended to carry all the parts required to stamp, cancel and stack the envelope. The casing 3 shows all the necessary gears to synchronously operate thevarious devices, and appear suiiiciently shown to be understood without further description. t may be said, however, that they a'remounted in bearings fixed to or integral with the table 2, and are raised therewith and exposed to inspection when it is lifted on its hinges.

Y The feerZer.-'l`liis is a device shown on the right of the main Figs. 1, 2, 3 and detailed inFigs. 4, 5, 6 and 7. Fig. 4 shows the gear 28 in the main casing 3, which drives a-bevel gear 27; and above this gear a spur gear 26. These three gears are 0f course mounted on av shaft designated 25. The bevel gear 27 drives a bevel pinion 17 which inits turn operates a spur gear 16; both are mounted on the shaft 1S, thespur gear 16 drives two pinion gears `15, both shown in. light lines in Fig. 5. The spur gear 26 drives a gear 24. All these are inclosedin casing 33, shown secured to the table 2, the top of'which is equal in height to the portion 10 of the table heretofore de- 2? is a side elevation of the same; and

scribed. The casing 33Y also partly incloses the two feed screws 11 which project slightly above the top thereof through suit-V able slots therein. The screw thread 11a `is shown enlarged in Fig.l 23, engages the' edges of the envelops and pressesthem forward and sidewise. In Fig. 1, the screws 11 are shown projecting out of the casing 33-l through slots 31, the screws or screw ro-llers being` inclosed on the left side by a wall 35, on the front by the angle wall 36,.on the right by a guard 201. An envelop driving V.roller 23 preferably faced with rubberis mounted so as to slightly project through V.the guard 201; it is driven by gear 24 previously described. Now, referring again to F ig. 1, a second envelop driving roller 37 is mounted just lat the angle formed by the walls and V.201 and on the table portion 10. A frictionfface 40 projecting slightly beyond the flanges of the roller is held in place by the ring flange 41, which' is fastened to flange 39 by screws 42; this roller is suitably mounted on shaft passing through bearing 47 and driven by gear 48 in the cas Y ing 3.

In order to assure the feed of `a Vsingle envelop from the container previ-V o-usly described, the opening left at the angle i formed by the wall 30 is closed by a set of three springs 51, 51 and49 shown inl Fig. 8.

The bar 56 carries a plate 54 to clamp springs 51, 51, by means ofa screw which also holds spring 49. The bar 53 is placed vin an opening formed in the wall 36, and

held in place by springs 59 also carriedby this same portion, as clearly shown in Fig. 7. The'springs 51, 51 bear on the flanges 39 and 41 and spring 49 on the frictionface 40 o-f the driving roller 37.

The operation of the feeder is as follows :V-Envelops irrespective of sizes, but having all the stamps facing to the left and downward, are placed overthe feed roller screws, as shown in Fig. 6. The screws revolve at a high speed, the envelop edges engage the threads and are immediately carried forward by the revolution of the rollers and sidewise by the threads. As soon as the frst'envelop comes in contact with the first driving roller 23, it is presented to the second driving roller 37, and contacts with the friction face 40 which draws it under the turned end 50of spring 49. Springs 51, 51 thenl come in action and press thepaper vfirmly against the friction face 40. As the wheel flanges lare lower than the friction face, the envelop is somewhat curved by the springs 51, 51; this curvature reduces the friction between the envelop passing and the next to it and assures positive disengagement. Y This feed is so positive in action that thousands of envelops will be delivered singly withoutmissing.

The. stamping device- As the envelop i leaves roller 37it' will be'engagedv by af V jl/)rinting'drum is an inking roller.

pressure roller 93.V See Figs. 18 and 14.`

This roller is provided with bearing surface 94 and journaledin Vaforled arm'9`6." `,This arinis swiveled to one end of a bell crank lever`98 pivotedon a pin 99 held in the post 100. A. tension spring 95l has its opposite ends. connected, respectively, to the end of f the-bell crank.leve1'98,"and to a post 101 projecting upwardly from'plate 2 and pulls to force the pressure roller 93 toward a printing drum. It' is not desired to allow the pressure roller 93Vto actually engage theV printing drum, becauseV there .must always be a slight'distance between them, butnot enough `to f prevent the pressure of an envelop against the printing drum as it passes along the letter way. Inorder to effect this separation, the free end ofthe yoke 96 is 'od set or curved slightly so as toengage ars'hort post 103 carried by a plate 102 which is pro`V vided with a longitudinal slot V104. Y; A cap screw 105 passes through this s'lotand is threaded into the rib 10.j Theprinting drum comprises a base-62 with an-annular wall '63 having TCCGSSGS Vand seatsf64 to receive removable type. or printing plates (S5-together with cap plates or segments 66 and train by a spur gear 70 made fast to the lower end thereof. VCoperating with the This ice roller shown indetail in'Fig. 15, comprises Y two plates ('9 and 80,*and an annular felt or other absorbent band'8`9 clampedbetween flanges 81 and 86, andfheld in place by theV flanges 82 and-87V. .When'the parts are assembled, theplate 79isprovided with a central; boss to receive a'jo'urnalpin or stud 72 on the swinging arm 73. y

The plate 80 is provided with an ink cup 88, with a central threadedbore by which Yit may be threaded into the part 85,'andwith a small hole 92 communicating with lthe chamber 91 formed between plates? 9 and 80,

and the band 89..V The arm 73 is journaled on apost 76 by means ofk a pin 77 passing through a' bore in one end of the arm andr j i threaded into the upper lend ofthe post.

VA coil spring` 78, mounted about the post 70,

and having oneend `in engagement with arm 73, serves to regulate the swingof the arm and presses the inlring roller on the printing drum. VThis ink distributer is found to bey very eective. The ink oozes out of the porous ring by Vcentrifugal forcefinzaneven and adequate manner. -Before Vthe envelop has completed fits passage between nthe stamping wheel and the friction roller 93,1t 1s caught by the rollers 1 06 and 107, 106'being the driving roller driven-by one of the train of gears underneath the table, 107V being the pressiueroller'whichY is mounted in a fork` Fig. 17,' by the numeral 110 ;y this recess, it

willY be noticed,ris in alinement withthe stamp on the stamping wheeland is intended to prevent thecontact ofthe freshly printed matter with the face of the roller.

VBy referring-to Fig. 16, it will be seen that friction roller 107, is mounted on a double cone shaft 10721. This 1s intended 'to allow the froller to rock Aand thereby adapt itself to the irregular thickness of Vmany envelops. The rollers 106 andl107 above de scribed are intended to deliver thel envelops to the canceling device to be presently described.

The `canceling device-As heretofore threaded on the shaft 157; this shaft passesthrough a bearing 158 which is mounted in a sleeve 159 `forming part of the bed plate 2; shaft 157 is revolved by gear 160 underneath the bed plate. The numeral 150 shows a groove on the face of the disk 14.19 forthe purpose later stated. The disks are mountved so asrto slightly project throughthe guide wall 200, and in order that the en velop may not bear too vheavily on the edges of the disks, idler rollers 205 are mounted on plate 200 as shown. Erasure of the color on a stamp by abrasion without tearing or cutting the paper, can be obtained only when the pressure on the reverse side is even and of the required force. In orderto obtain this desideratum, long `and careful experiments were required. Y

On the rib-10, near the projecting Aedges of the disks is adjustably mounted a plate provided with an elongatedslot 117,

adapted to slidably receive a bolt or threaded post 116 projecting upwardly from the rib 10. A nut is'turned down upon the projecting threaded end and serves to bind the Aplatein any of its various adjusted positions. VAtthe opposite end of this plate and on the side nearest the wall 200 are provided two posts 118 and 119, on the lower partof which are rotatablyunounted two sleeves 120 and 121. Eachsleeveisprovided with a lever arm 122 and 123, and each lever arm carries a rod or'post 125, also each lever arm has at its free enda tubular boss 124 adapted to receive a pin 140 which may be passed therethrough and engage with any one of the holes 14:1, in the plate V115 (see Figs. 19 and22). Above the sleeves120 and 121 are similarly Vmounted sleevesi126 and 127 provided with elbow arms 128 and 129, the arm 128 crossing;and overlying the arm 129 at the elbow. (See Figs. 20 and 21). The arm 128 carries on its outer end a small pressure roller 132 freely rotatably mounted on a` screw post, a stud or the like 130. The arm 129 'carries a pressure roller 131, in the same way. It is desirable of course, to have both rollers in the same line,so that the line or pressure will be continuous. Therefore a'spacing washer is placed beneath the roller 131 to raise it to the same plane as roller 132. In order to keep the Vrollers v131 and 132 in operative engagement coil springs 139 are used. These are coiled about the sleeves 126 and 127, and have their opposite ends engaging one of the arms 128 and 129, and one of the posts or rods (see Fig. 19), carried by swinging arms 122 and 123 aspreviously disclosed; the tension of these springs corresponds to the regulation of the pressure onvthe rollers 131 and i 132. As shown in Figs. 19 and 21, the pressure of the springs 139 is applied close to the pivots of the arms 128, 129, 135, and 136. As these arms are of considerable length, the slight extent of movement of the 11" ends of these arms as a thick or a thin envelop passes thereunder'causes so slight a variationof spring pressure that this pressure is practically evenor uniform on a thick or thin envelop, and the abrasion of the stamps is effected without danger `of injury to the envelop or its contents. Above Y sleeves 126 and 127 is a third set of sleeves 133-134, with elbow arms 135 and 136,

carrying rollers 137 'and 138, and having actuating springs 139, all arranged and constructed similarly to those already described. The rollers 131 and` 137 are intended to act more as guide rollers to receive the mail matter as it comes along the letter way and guide it to the second set of rollers 132 and 138. Consequently they must exert less pressure on the mail matter than the corresponding set of rollers. rfhis pressure is derived from their corresponding springs 139, while the pressure of rollers 132 and 138 is obtained from the springs of both sets in the following manner: Just at the elbow of each of the arms 129 and 136 a stop pin 162 is secured asthe elbows of Var1ns1128 and ,.135

action of the canceling disks.

arerespe'ctivelyi'n contactwith these pins it ywill beV evident thatf as soon as the mail matter comes in contact with rollers 132 and 138, a locking of all the four.` arms 128, 129,V .135; and i136 is effected and theirrespective Vsprings. contribute to a combined pressure It must be borne in mind that at the time the mail matter begins to pass between the disks and the rollers 131 andV 137, it isstill being fed toward them by rollers 106 and 107, rollers 106 and 107 rotate at a much slower speed than the canceling disks. The result is that the rollers 106 and 107 really hold the envelop back against the pulling This retardation causes the disks to abrade and thereby cancel the stamp. ln order to regulate the distance between the disks and coperating rollers, a plate 142 is provided having an elongated slot 146. Said plate is mounted on a post 145 on the plate 115 and made adjustable bymeans of a screw 147; it is provided with a cross arm having ends 143 and 144, each adapted to engage one pair of the elbow arms. As will be apparent from Fig. 19, thc envelop as it passes between the adjacent sets of spring pressed disks and the grinding wheel, isV given a very slight longitudinal bend; and as will vbe apparent from Fig. 20, since the spring-pressed disks 131, 132, 136, 137, face the space between the peripheral grinding edges of the abrading wheels, there will be a'slight lateral bending, or a tendency to such bending, of the envelop. The pressure which holds the envelop against the abrading edge is not directly applied against said edge but to one side thereof, thereby permitting Va slight yielding of the envelop. From the can-` eeling device', the mail matter continues along to a collecting rackcomposed of a plurality of spaced parallel rods fastened to the rib 10 and to bar 165. This rack is braced by Va bar 166 as shown. At the upper end thereof, and extending along the rib 10, isa guide wall 163. The portion near the end of wall 200, is deflected or off-set to provide a passage forthe mail matter. y To check the traveling velocity of the envelop, stop 167 is provided. It is made adjustable to various lengths of mail matter by providing same with a V shaped base adapted to be slidably mounted onthek guide wall; it may be securely fastened in various adjusted positions by a screw 168.V This stop of course prevents the mail from being driven beyond the collecting rack. Slidably mounted on one of the bars 164 is a second stop in the form of a plate 169 with a slot- :ted ytubular base 17.0 .and friction leaf spring` 171; when the `manne-is Starred,- rhisstop is moved :along thebar 164'toward the wall 163 'tofaQposition .whichy will havejust venoughrspac'e between -it and the wall for one envelop. Coperating'with this stop is .a packer comprising two similar wsets of bent arins 173, fixed to a short'lvertical shaft174.

journaled in a boss on plate 2. The'lower endof the shaft carriesfa driving gear 175 which is engaged and driven bythe clock train gears, as will later appear. lheibent arms lproject slightlygthrough slots in the i wall 163 as they are rotated, and engage theV mailmatter as it collects between the wall 163 and the Vstop 169, exerting a packing ac-V tion Lwhich gradually forces 'the stop 169.A

back along its 'rodl 164toward the bar 165,

but at all times insuring al solid compact bundle-which may be removed from timetov time.,` w Y Y For driving the several mechanismsa Inotor 176, belt .178,v and differential pulleys *Y i 177 are provided. Pulleys 177 are made fast to the shaft 179.journaled 1in a bearing 180 in the casing 3 and having fixed toits inner end a bevel pinion 181 which meshes `with and drives a bevel gear 182 fixed to a shaft 183 which is journaled inthe boss 184. VTo the lower end of this same shaft is also fixedV a gear 185 which meshesvvith and drives gear 175 of the packer. VGrear 185 also meshes with and drives a small gear 186 fixed on a stub shaft 187freely revoluble in a boss on the under side of cover'2.i To the other end of stub shaft187 is fixed a gearl 192. The pinion 186 meshes with and drives gear 109, fixed to shaft 108 thereby driving roller 106. The gear 192 drives pinion 160,

of much smaller diameter and is lfastened toi shaft 157' thereby driving the canceling disks 149 at a much greater speed than roller 106. Shaft 108 also carries a` pinion 188 which meshes with apinion 189 on stub shaft 190; pinion 189. in turn meshes with andjdrives'the gear 70 on the shaft 68.0f the printing drum. The samesha'ft carries a gear 191whieh `meshes with andy drives gear 48 which is fixed to and drives the shaft 45 ofthe second feed roll 37 and the gear 48. in turn drivesthe gear 28.
